feat(Database): Add support for parsing booleans

[dannyboy15]

Add the ability to parse (sql) booleans. By default the option is turned off, to ensure current workflows don't unintentionally get altered.

To turn on boolean parsing set

DatabaseCreateStatement.DO_PARSE_BOOLS = True

It might be easier to toggle the Boolean parsing on or off (especially in the test suites) if we pass it as an optional argument in this function, instead of the config setting on the base class. Something like:
def detect_data_type(self, value, cmp_type=None, do_parse_bools=False):

@dannyboy15 I added the requested changes about separate test cases for the DB boolean parsing... I think you might have had some other ideas about how to approach but merging this in now to keep it current. Feel free to submit another PR if you want to modify the approach!
